The Define Instruments 24V power supply is designed differently from a general purpose power supply. Emphasis is placed on withstanding and rejecting EMI events. This is achieved by second and third stage filtering in both common and normal mode configurations, and shielding to reject unwanted signals. This combination eliminates the need for a Y cap between the primary and secondary, increasing the impedance to high frequency transients by an order of magnitude or more.
